SHOCK-LOADER.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed May 22, 1906. Serial No. 318,166.

shocked crops, such as corn, may be readily lifted from the ground to the Vehicle and retained in place thereon during transportation.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation ofa vehicle embodying my invention; Fig. 2 a rear end elevation with the pawl mechanism omitted; Fig. 3 a detail on a larger scale, of the winding drums; Fig. 4 an elevation of the right hand end of Fig. 3; Fig. 5 a section on line 55 of Fig. 3; Fig. 6 a detail of the power-drum; Fig. 7 a detail of the platform-lifting ropes; Fig. 8 a detail of one of the pawls, Fig. 9 a section on line 99 of Fig. 1; Fig. 10 a side elevation of a modified form; and Fig. 11 a rear elevation with the pawls omitted.

In the drawings, 10 indicates a vehicle, such as an ordinary farm-wagon-runninggear, upon which is detachably mounted a frame 10 provided at its ends with posts 11, 11, the upper ends of which are firmly connected by a longitudinal bar 12 upon which is hung, or otherwise supported, a plurality of pulley blocks 13, said pulley blocks being arranged at suitable distances along the length of the bar 12 at about the distance occupied by the shocks which are to be handled. Hinged upon frame 10 are two inwardly folding platforms 1 1, 14 upon which the material is to be deposited. Running through each pulley block 13 is a lifting cable 15 and each of said lifting cables is passed over one of a series of idle pulleys 16 supported at the upper end of the rear post 11. Journaled in suitable bearings at the rear of the frame 10, and as low down as may be convenient, is a Windlass shaft 17 which may be operated by thehand crank 18 geared thereto; Crank 18 is carried by a shaft 19 journaled in a pivoted head 20 and carrying a worm 20 meshing with a worm wheel 21 attached to shaft 17, the arrangement being such that the worm may be lifted away from the wheel and held out of engagement by a pin 22.

Mounted loosely upon shaft 17 isa drum 23 upon which is wound a cable 24 which may be attached to a suitable draft'animal. Drum 23 is connected to shaft 17 by a clutch connection 25, and is provided with a suitable handle 23 by means of which the cable may be rewound upon the drum.

J ournaled upon the shaft 17 is a plurality of winding drums 26, there being as many as there are lifting cables 15, and each of said lifting cables is carried to one of said winding drums. In order to connect any one of the winding drums 26 to the shaft 17 I provide each drum with a hub 27 diametrically perforated or slotted at 28 for the reception of a pin 29 which may pass through a registering perforation 30 in the shaft Each drum 26 is provided on the rim of one of its flanges with ratchet teeth 26 and a series of pawls 31 is arranged on a shaft 32 in position to engage such teeth, a separate pawl being provided for each drum 26.

Shaft 32 carries a series of fingers 33 adapted to engage pins 3 f carried by the pawls 31 so that by turning the shaft, all of the pawls may be simultaneously withdrawn from their drums. In order to with draw any one of the pawls, each pawl is provided with an arm 31 having an inclined surface 31 and adjacent each pawl is a lever 35 adapted to engage said surface to swing its pawl away from its drum.

In order to lift the platform 14 I provide a pair of ropes 40, 40 which descend at opposite ends of the platforms and are provided with hooks 11 adapted to enter one or the other of the eyes 42 attached to the inner ends of the platforms 1d. The two ropes lO are brought over an idler 4:3 and attached to a single rope 44: which is led to one of the drums 26.

The operation is as follows: The vehicle will be driven up alongside a shock and one of the lifting cables 15 attached thereto. The corresponding drum 26 will then be connected to the shaft 17 in the manner already described and shaft 17 rotated, either by hand, or by the draft animal, so as to wind the said cable 15 uponits drum 26. hen the shock has been lifted to the platform the cable 15 will be allowed to remain in engagement withthe shock, and the corresponding pawl 31 will hold the drum against reverse rotation. The operation will be repeated with a different cable 15 until the vehicle is loaded. hen the load is to be discharged the cables 40 are attached first to one platform 14 and then the other and the inner end of the platform lifted, as shown in dotted lines in Fig. 2, until the shocks slide off, their attachment to the cables l5 preventing them from tipping over on their sides.

In Figs. 10 and 11 I show a construction by means of which the greater part of the work of lifting the shock may be accomplished automatically as the machine is driven to the next shock. In this form I journal a sprocket wheel 50 on the shaft 17 and connect it to the shaft by any suitable separable clutch mechanism, as for instance the removable pin 51. lVheel 50 is connected by a chain 52 with a sprocket wheel attached to one of the vehicle wheels 54'. In operation; the shock will be lifted just clear of the ground, in the manner aready described, by means of the hand crank 18 and worm 20. Wheel 50 will then be connected with the shaft 17 and worm 20 thrown out of engagement with worm-wheel 21. The vehicle will then be driven forward to the next shock and, as it moves forward, the shock will be automatically lifted to the platform. It will be noticed that the cables 15 may be extended laterally from the vehicle in opposite directions and that when shocks are lifted by the several cables onto the vehicle said shocks are arranged close to the middle line of the vehicle and bal anced on each side so that there is no danger of the vehicle tipping over either during the progress of loading or transportation. The

. load is also well centralized so that it may be driven through standard gates.
